Pillars of the Eagle Nebula in Infrared
20.06.2018
Newborn stars are forming in the Eagle Nebula. Gravitationally contracting in pillars of dense gas and dust, the intense radiation of these newly-formed bright stars is causing surrounding material to boil away. This image...
Ancients of Sea and Sky
19.06.2018
They may look like round rocks, but they're alive. Moreover, they are modern versions of one of the oldest known forms of life: stromatolites. Fossils indicate that stromatolites appeared on Earth about 3.7 billion years ago -- even before many of the familiar stars in the modern night sky were formed.
An Active Prominence on the Sun
18.06.2018
Sometimes the Sun's surface becomes a whirlwind of activity. Pictured is a time-lapse video of the Sun's surface taken over a two hour period in early May, run both forwards and backwards. The Sun's surface was blocked out so that details over the edge could be imaged in greater detail.
Mars Engulfed
17.06.2018
What's happened to Mars? In 2001, Mars underwent a tremendous planet-wide dust storm -- one of the largest ever recorded from Earth. To show the extent, these two Hubble Space Telescope storm watch images from late June and early September (2001) offer dramatically contrasting views of the martian surface.
Dusty With a Chance of Dust
16.06.2018
It's storm season on Mars. Dusty with a chance of dust is the weather report for Gale crater as a recent planet-scale dust storm rages. On June 10 looking toward the east-northeast crater rim, the Curiosity rover's Mastcam captured this image of its local conditions so far.
Little Planet Soyuz
15.06.2018
Engines blazing, a large rocket bids farewell to this little planet. Of course, the little planet is really planet Earth and the large rocket is a Soyuz-FG rocket. Launched from the Baikonur Cosmodrome in Kazakhstan on June 6 it carried a Soyuz MS-09 spacecraft into orbit.
Six Planets from Yosemite
14.06.2018
The five naked-eye planets, Mercury, Venus, Mars, Jupiter and Saturn, have been seen since ancient times to wander the night skies of planet Earth. So it could be remarkable that on this night, standing at the side of a clear, calm lake, six planets can be seen with the unaided eye. Have a look.
Red Cloudbow over Delaware
13.06.2018
What kind of rainbow is this? In this case, no rain was involved -- what is pictured is actually a red cloudbow. The unusual sky arc was spotted last month during sunset in Rehoboth Beach, Delaware, USA.
Star Size Comparison 2
12.06.2018
How big is our Sun compared to other stars? In dramatic and popular videos featured on YouTube, the relative sizes of planets, stars, and even the universe are shown from smallest to largest. The featured video begins with Earth's Moon and progresses through increasingly larger moons and planets in our Solar System.
At Last GLAST
11.06.2018
Rising through a billowing cloud of smoke, a long time ago from a planet very very close by, this Delta II rocket left Cape Canaveral Air Force Station's launch pad 17-B at 12:05 pm EDT on June 11, 2008. Snug in the payload section was GLAST, the Gamma-ray Large Area Space Telescope.
